We are trying to deenvelope inbound CII messages on POD21 and send post translated flat file data to Freescale. During deenveloping process, it is triggering MULTIPLE outbound enveloping steps for CII, X12 and EDIFACT as well when we have inbound CII envelope is set to generate acknowledgement message. We are not sure why it is triggering enveloping step for other EDI standards like X12 and creating documents for other customers on POD21 (completely irrelevant document types and customers). This data for other customers is getting tracked under Freescale inflight instance and it is using Freescale routing rules to process them through GIODE. If we turn off ACK generation setting, it is working fine. This behavior is completely random (sometimes it works fine, sometimes it triggers data for other customers) and it is impacting CII data processing for Freescale when we have acknowledgements turned on.
